The key chip will break. But the bad ones are probably very small.
The chip is a password of the manufacturer's lock on the ignition, and the matching chip is one-to-one corresponding to the ignition system, even if the key is inserted in but the chip does not match, it can not be started, the chip can be said to be just a passcode point does not fire.
Can not start it may be a chip problem to start a good sudden flame out with the chip is nothing to do with the oil supply or intake problems, check the gasoline pump and throttle, oil and intake.

Solution of automatic flameout:
1. Vibration method
When vibration may be the cause of the failure, the vibration method can be used to solve the problem. The basic methods are:
Gently shake the connector in vertical and horizontal directions; Gently shake wiring in vertical and horizontal directions; Tap the sensor part with your finger to check whether it is turned off, but do not beat the relay hard, otherwise it will damage the sensor part.
2. Heating method
If some faults occur only when the car is hot, it may be caused by the heat of the relevant parts or sensors, you can use a hair dryer or similar heating tools to heat the parts or sensors that may cause the failure to check whether there is a fault. However, it must be noted that the heating temperature should not be higher than 60℃; Do not directly heat parts in your computer.
3. Water shower method
When some faults occur in rainy days or high humidity environments, water can be sprayed on the vehicle to check whether there is a fault. However, it should be noted that the water should not be sprayed directly on the engine electronic control parts, but should be sprayed in front of the radiator to indirectly change the humidity and temperature; Do not spray water directly on electronic components, especially to prevent water from entering the computer.
4, electrical fully connected method
When it is suspected that the fault may be caused by too much power load, all electrical equipment can be connected to check whether there is a fault.
